Summary
N3T Projekt
business poland small
N3T-AS is operated by N3T Projekt, a Polish entity registered under Mariusz Ufel.
What it's used for
- The address space carries business and office traffic, evidenced by reverse DNS entries pointing to
rev.n3t.pland netnamesN3TandPL-N3TPROJEKT-20221122. - The AS announces 768 IPv4 addresses across 3 prefixes with 6 observed neighbours, a ratio consistent with a small business or enterprise network rather than a transit provider.
- Traffic from this AS consists of internal corporate communications and web endpoints for the N3T Projekt organization.
Notable
- Registrants for the two 81.6.x.x/24 prefixes are listed as
Kielman NOC, while the 193.104.233.0/24 prefix is registered toN3T; Mariusz Ufel trading as N3T Projekt, indicating a potential historical or operational split in address management. - The inventory consists of three /24 blocks, all located in Poland, with no IPv6 prefixes announced.

Reputation
Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 443 networks and 1,779 prefixes, as published 2026-10-24. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
